Technical Field

The invention relates to a tool for manufacturing a ship, in particular to a support frame for assembling a ship energy-saving guide pipe.

Background

The energy-saving guide pipe is arranged on a tail shaft hub of the ship body tail shaft section, five fin plates are arranged in the middle of the energy-saving guide pipe, the fin plates are processed according to the shape of the rear propeller, when water flows through the energy-saving guide pipe, a rotating water flow is formed, mechanical force required by rotation of the propeller is reduced, oil consumption can be reduced, and an energy-saving effect is achieved. The energy-saving guide pipe for the ship can effectively save oil consumption by 7 percent, so that the energy-saving guide pipe arranged on the ship is a new green and environment-friendly measure and is popular among shipowners. However, since the last section of the tail shaft segment is made of cast iron, the line type of the tail shaft hub cannot be determined due to uncertainty of the line type of the sand blank when the cast iron is poured, and therefore, a margin of 150mm is placed when the energy-saving guide pipe is manufactured, and difficulty is brought to the overall assembly of the energy-saving guide pipe. At the beginning, the energy-saving guide pipe is hoisted, four supporting seats are used for supporting the lower end of the energy-saving guide pipe, then the energy-saving guide pipe is adjusted to be horizontal, is aligned to the central line, sets a preliminary allowance, and is reset by a gantry crane after cutting. And the time is 5 days from two to three times of positioning and resetting until the energy-saving guide pipes are completely in place, and the number of times of hoisting and resetting by using the gantry crane reaches 5 times, so that the production efficiency is low, and the repeated use of gantry crane for resetting not only influences the hoisting of subsequent subsections, but also increases the load of the gantry crane and influences the completion of production plans of departments.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a support frame for the total assembly of the energy-saving guide pipe of a ship, which can reduce the hoisting and resetting times of a gantry crane, can displace and position the energy-saving guide pipe at any time and quicken the total assembly and positioning time of the energy-saving guide pipe.

The purpose of the invention is realized as follows: a supporting frame for the general assembly of a ship energy-saving guide pipe comprises a left side bracket, a right side bracket, an upper connecting rod, a lower connecting rod and four supporting pipes, wherein,

the left side bracket and the right side bracket have the same structure and respectively comprise two rectangular frames and four short connecting rods connected between four corners of the two frames, and the two frames and the four short connecting rods are all made of square steel with the same size;

the upper connecting rods and the lower connecting rods have the same length and are connected between the upper rear ends and the lower rear ends of the left side support and the right side support in a one-to-one correspondence manner; the upper connecting rod and the lower connecting rod are both made of square steel with the same size;

the four supporting tubes are welded at the front end and the rear end of the top surface of the left bracket and the front end and the rear end of the top surface of the right bracket in a one-to-one correspondence manner;

the left side support and the right side support are respectively arranged on two docking blocks and two three-dimensional adjusting jacks.

The support frame for the overall assembly of the ship energy-saving guide pipe is characterized in that a plurality of stand columns are further arranged in each frame at intervals.

The support frame for the ship energy-saving pipe total assembly is characterized in that the two docking blocks and the two three-dimensional adjusting jacks are arranged at intervals in a staggered mode.

The technical scheme of the support frame for the total assembly of the ship energy-saving guide pipe has the following characteristics:

1. the energy-saving guide pipe can be finely adjusted by matching with a three-dimensional adjusting jack, so that the hoisting reset times of the gantry crane are reduced; the saved time can organize the gantry crane to carry out other hoisting operation;

2. the energy-saving guide pipe can be displaced and positioned at any time, and the total assembly time of the energy-saving guide pipe is shortened.

Detailed Description

The invention will be further explained with reference to the drawings.

Referring to fig. 1 to 3, the support frame for the total assembly of the energy-saving conduit of the ship comprises a left side support 1, a right side support 1 ', an upper connecting rod 2, a lower connecting rod 2' and four support tubes 3, wherein,

the left side bracket 1 and the right side bracket 1' are identical in structure and respectively comprise two rectangular frames 11 and four short connecting rods 12 connected between four corners of the two frames 11, and three upright posts are arranged in the rectangular frames 11 at intervals so as to enhance the rigidity of the frames; the two frames 11 and the four short connecting rods 12 are all made of square steel with the same size;

the upper connecting rods 2 and the lower connecting rods 2 'have the same length and are connected between the upper rear ends and the lower rear ends of the left side bracket 1 and the right side bracket 1' in a one-to-one correspondence manner; the upper connecting rod 2 and the lower connecting rod 2' are both made of square steel with the same size;

the four support tubes 3 are welded at the front end and the rear end of the top surface of the left bracket 1 and the front end and the rear end of the top surface of the right bracket 1' in a one-to-one correspondence manner; the support tube 3 is made of a round tube;

the left support 1 and the right support 1' are respectively installed on two docking blocks 4 and two three-dimensional adjusting jacks 5, and the two docking blocks 4 and the two three-dimensional adjusting jacks 5 are arranged at intervals in a staggered mode.

The use method of the support frame for the total assembly of the ship energy-saving guide pipe comprises the following two steps:

1. according to the position of a stern shaft section 6 which is placed on two section supporting frames 60 in a front-end-down mode, a position ground sample line of an energy-saving guide pipe 7 is marked on the ground, then two docking blocks 4 and two three-dimensional adjusting jacks 5 are respectively placed on the left side and the right side of the energy-saving guide pipe 7 on the ground according to the position ground sample line of the energy-saving guide pipe 7, the two docking blocks 4 and the two three-dimensional adjusting jacks 5 are arranged at intervals in a staggered mode, then a left side support 1 and a right side support 1 ' are respectively hung on the two docking blocks 4 at the corresponding positions, a supporting pipe 3 on the left side support 1 and a supporting pipe 3 on the right side support 1 ' are just positioned at the position of the energy-saving guide pipe 7, then an upper connecting rod 2 and a lower connecting rod 2 ' are welded between the left side support 1 and the right side support 1.

2. Firstly hoisting the energy-saving guide pipe 7, enabling the energy-saving guide pipe 7 to be just located on the four support pipes 3 in a mode that the front end face of the energy-saving guide pipe is downward, then using the three-dimensional adjusting jack 5 to jack the support frame for the energy-saving guide pipe assembly in the height direction, displacing in the front-back direction and displacing in the left-right direction, determining a primary allowance and cutting after reaching a certain position, then using the three-dimensional adjusting jack 5 to adjust, determining a secondary allowance and cutting after reaching a certain position, and thus carrying out position adjustment and allowance cutting for a plurality of times until the energy-saving guide pipe 7 reaches a theoretical position, and then welding the energy-saving guide pipe 7 and the stern shaft section 6.
